For customer-side coating
Zinc and zinc-nickel plating run on our own line in Ningbo, so coating thickness and passivation are checked on every batch. Zinc-nickel (12–15% Ni) is the option when a part needs long corrosion life, for example under a car or outdoors.
| Zn-Ni thickness | Neutral salt spray |
|---|---|
| 12 µm | 1,000 h to first red rust |
| 15 µm | 1,440 h to first red rust |
